[gcjx] Add -fdump-tree for dumping AST

Hi,

  The attached patch is my attempt to add an "-fdump-tree" option
to the standalone compiler that uses the pretty-printer to
dump the AST of a file after compilation. The actual dumping
happens after semantic analysis in compiler::do_analyze_unit().

If nothing, this would help compiler newbies like me to
understand what AST GCJX builds from a given source file.
It might perhaps come handy in debugging the compiler too.

Note that even after this patch the compiler doesn't
seem to output anything when -fdump-tree is specified.
This is simply because pretty_printer::visit_unit_source()
is unimplemented as of now and I would implement it real
soon now.

Does this look acceptable?

Thanks,
Ranjit.
